UNITED STATES PATENT OFFICE.
JAMES B. SCHUMAN, OF COLUMBIA CITY, INDIANA, ASSIGNOR OF THREE- FOURTHS TO JOSEPH K. SHARPE, JR, AND AUGUSTIN BOIOE, OF INDIAN- APOLIS, INDIANA.
AUTOMATIC WEIGHING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 686,544, dated November 12, 1901. Application filed August 15, 1900. Serial No. 26,910. (No model.)
To all whom, it may concern.-
Be it known that 1, Litres B. SOHUMAN, a citizen of the United States, residing at C- lumbia City, in the county of Whitley and State of Indiana, have invented a new and useful Automatic VVeighing-Machine, of which thefollowing is a specification.
My invention relates to an improvement in automatic weighing-machines, and especially to that class in which the material to be Weighed is deposited in sacks, bags, or other receptacles. v
The object of my invention is to produce an automatic Weighing-machine of the class described which shall be simple in construction and positive in action.
A further object is to provide means for antomatically shifting or changing the direction of flow of the material to be weighed and to provide adjustable means for holding sacks or receptacles of various sizes.
The accompanying drawings illustrate my invention.
Figure 1 is a perspective View of my invention. Fig. 2 is a vertical section. Fig. 3 is a sectional detail on an enlarged scale. Fig. 4. is a similar detail showing successive positions of parts.
In the drawings, 5 indicates a base having secured thereto a pair of uprights 6, to the upper ends of which is secured a frame 7, to which is pivoted at S a weigh-beam 9, having a suitable poise 10 mounted thereon. The inner or short arm of beam 9 is bifurcated,
3 5 and upon the end of each leg is pivoted at 11 a segment 12. Each segment 12 is provided with a pair of pins 13 and 13, which are ar ranged at equal distances upon opposite sides of the medial line of the segment and lie parallel to the pivot 11. Pivoted upon each pin 13 by means of a slotted opening 15 is a link 16, to the lower end of which is pivoted one of the uprights 17 of a bag-supporting platform 18, the weight of the platform when in its raised position being thus supported, through links 16, pins 13, and segment 12, by the beam 9. Similarly links 16', having slotted openings 15, are mounted upon pins 13 and support uprights 17' of a bag-platform 18.
Pivoted to each upright 6 near its lower end is an arm 19, to the ends of which are pivoted links 20 and 20, the free ends of which links are pivoted, respectively, to the uprights 17 and 17, the arrangement being such that a substantially vertical movement of the bag-platforms is obtained, the movement of each platform being, however, unaf fected by the other except through segment 12. Projecting radially from each segment 12 is a pair of stops or pins 21 and 21', which pins are so arranged that they may be alternately brought vertically over the pivot 11.
Pivoted upon frame 7 above each segment 12 and upon each side of the medial line at some distance therefrom and upon an axis parallel to the axis of said segment is a pair of dogs 22, the free ends of which lie toward the medial line and carry rollers 23. The adjacent peripheries of said rollers are separated a distance but slightly greater than the width of either of the stops 21 and 21, and the arrangement is such that the said stops may be inserted between the rollers and held thereby.
Leading from frame 7 is a pair of dischargespouts 25 and 25, the mouths of which lie immediately above platforms 1S and 1S, respectively. Pivoted upon an axis 26 parallel to the pivots 11 and immediately above the point of junction of the inner sides of spouts 25 and 25 is a deflector-plate 27, which maybe swung so as to deflect the material to be weighed into either one of said spouts. In order to automatically operate the deflector-plate, I secure to one of the segments 12 an arm 28, provided with a pair of fingers 29, said fingers being so arranged that when the segment is swung upon its axis from one extreme to the other the rear finger will be carried slightly beyond 0 a point vertically above axis 26. Secured to the free end of deflector 27 is an arm 30, which projects between and is adapted to be engaged by fingers 29 of arm 28.
In order to properly support the mouths of 5 bags beneath the spouts 25 and 25, I secure to each pair of uprights 17 17 a bar 31, provided with a vertical slot 32, adapted to receive a bolt 33, upon which is also secured a cross-arm 34. Arm St at each end is bent outtoo ward and upward and provided with a T-' head 35, upon each end of which is formed an outwardly-projecting prong 36. Arm 34 may be vertically adjusted and held in any desired position by means of a nut 37 upon bolt 33.
The material to be weighed may be introdu ced: into the machine by any desired means-as, for instance, a hopper 38, (shown in dotted lines in Fig. 3,) discharging immediately above deflector 27.
The normal position of the parts is such that one or the other of platforms 18 and 18 is lifted above the base while the other rests thereon. Taking the parts in one of the normal positions, as shown in Fig. 1, the operation is as follows: An empty sack is placed upon each platform, its upper end being turned over and outward, so as to be caught by the prongs 36, and thus held immediately below the corresponding spout. The grain or other material flowing through the supplyspout falls upon deflector 27, and is thereby deflected into spout 25 and from there into the sack upon platform 18. As soon as sufficient material has passed into the bag to counterbalance the poise 10 of beam 9 the weight thereof will be sufficient to depress the inner end of the beam, and thus withdraw pin 21 downward from between rollers 23, the said rollers preventing any rotation of the segment 12 until the said pin 21 has been practically withdrawn. The weight of the grain in the sack then causes a partial rotation of segment 12 in the direction indicated by the arrow in Fig. 4, thus bringing pin 21 into engagement with one of the rollers 23 and forcing said roller upward out of its path. At the same time the platform 18 comes to rest upon base-5 and a continued rotation of the segment is produced by the return swing of the beam and consequent upward movement of pivots 11. This movement of the segment brings pin 21 close to the forward roller 23, so as to allow the rear roller 23 to drop behind said pin. At the same time platform 18, through link 16 and standards 17, has been raised so as to occupy a position corresponding to the original position of platform 18, and is thus brought into operative connection with the weighbeam, While at the same time platform 18 is thrown out of operative connection. It is to be noticed that owing to the slotted connec= tion between links 16 or 16, and the segment 12 one platform is entirely disconnected from the segment while the other platform is receivingits weight. In other words, the connection between the segment and each platform is such as to allow a relative movement between each platform and the segment, so that in operation each platform is practically entirely disconnected from the segment and the weigh-beam when the other platform is connected and in position to receive its weight. The movement of segment 12 swings arm 28 until the rear finger 29 passes the center, the said rear finger, through pin 30, swinging the deflector-plate 27 slightly beyond the vertical, so that the weight thereof, together with the incoming and continuous stream of material to be weighed, causes a continued movement of said plate, so as to bring rod 30 into engagement with the other finger 29, thus deflecting the material to be weighed through spout 25 into the bag on platform 18.
'While the operation just described is being repeated the operator removes the full bag from the platform 18 and puts an empty one in its place, the operation of filling, weighing, and shifting continuing and being entirely automatic.
I claim as my invention- 1. In an automatic weighingmachine, a weigh-beam, a pair of weight-receiving members, a swinging segment mounted upon the weigh-beam, connections, permitting relative movement between said segment and said weightreceiving members upon opposite sides of the axis thereof, means independent of the weigh-beam for supporting the weightreceiving members, a pair of stops projecting from said segment and adapted to be inserted between the dogs, and a pair of dogs arranged to engage said stops, whereby the weight-receiving members may be brought automatically and alternately into engagement with the beam by weight applied to the other weightreceiving member.
